Definitions

  • the invention relates to a method for producing an automobile body molding or a blank therefor according to the features specified in the preamble of claim 1.
  • Molded body parts as they have been used millions of times in the automotive industry for decades, are manufactured cost-effectively in large numbers.
  • a sheet metal coil is used as the starting material, which is cut into plate-shaped sections and then straightened.
  • Such a usually rectangular sheet metal section is then cut to size according to the shape of the molded automobile body part to be produced and subsequently deformed with a deep-drawing or pressing tool. It is essential that the surface of the workpiece remains smooth and undamaged right up to the edge in order to avoid further post-processing before painting.
  • the present invention is based on the object of improving a method for producing a molded automobile body part, in particular for producing a blank from a sheet metal section, to the effect that the aforementioned disadvantages do not occur, in particular thin sheets of aluminum can also be produced inexpensively. Furthermore, the device-related training required for this is to be made available in order to be able to carry out such an improved method.
  • the basic idea of the present invention is not to cut out the blank from a thin sheet metal section by means of a laser beam as in the prior art, to produce a blank from a sheet metal section for the production of an automobile body molding, but to provide a machining process for cutting out the blank and to use a thin sheet section made of light metal .
  • This method can be used particularly advantageously in the method for producing an automobile body molding in which, following the blank, there is a plastic deformation to form a hollow body which forms the later automobile body molding or at least a part thereof.
  • very high quality requirements can be met, both with regard to the absence of structural changes due to the cutting and with regard to the high surface quality of all side surfaces, including the cut surface, that can be achieved with it.
  • the method according to the invention is particularly advantageous for producing blanks from sheet metal sections which are made of light metal.
  • light metal can be machined particularly well; on the other hand, when the method according to the invention is used, especially when using light metal, the structural changes occurring in thermal cutting processes in the area of the cutting surfaces do not occur or at least not noticeably.
  • molded automobile body parts, or at least parts thereof can be produced inexpensively with high accuracy and high surface quality, even in small and medium-sized quantities.
  • the cutting out of the blank is according to the invention by milling, in particular done by high speed cutting.
  • This milling typically does not require cooling or lubrication during cutting.
  • Small, light machines of known design can be used.
  • the milling cutters to be used in this connection which have a diameter of 6 mm, for example, have a long service life and are inexpensive to procure. They allow high cutting speeds and thus economical production of the blanks.
  • one or more identical or different milling cutters with appropriate drives can be used.
  • suction of cutting particles is provided during the cutting process when cutting out the blank.
  • a suction takes place advantageously through one or more suction nozzles positioned directly next to the milling cutter or advantageously also through a central suction nozzle surrounding the milling cutter.
  • the cutting forces occurring during high-speed cutting of thin aluminum sheets of the aforementioned type are comparatively low, but it is always necessary to fix the workpiece in a suitable manner during processing.
  • the cutting out of the blank takes place on a milling machine, preferably a portal milling machine, which has a machine table on which the sheet metal section is held during the cutting by vacuum clamping technology.
  • Vacuum clamping technology is not only a cost-effective clamping method that is advantageous in terms of workpiece change, but is also particularly suitable for obtaining a high surface quality, as the otherwise common two-sided clamping is no longer necessary.
  • the suction the workpiece surface becomes large loaded so that damage to the sensitive workpiece surfaces can be avoided without special precautions.
  • a machine table for clamping a sheet metal section is provided according to the invention, which is advantageously used when cutting out a blank according to the method according to the invention.
  • the machine table according to the invention for clamping a sheet metal section has a large number of recesses, in particular bores in the upper side and workpiece support surface of the table, which are line-connected to a vacuum source, for example a vacuum pump, in order to suck in the workpiece on the workpiece support surface and thus fix and assign it on the machine table tighten.
  • the workpiece support surface has at least one preferably recess-free groove, the course of which corresponds at least in sections to the contour of the blank to be cut.
  • the groove is advantageously dimensioned such that a free space is formed for the cutting tool during cutting.
  • the basic idea of the machine table according to the invention is therefore to create a free space for the cutting tool, that is typically the milling cutter, through the groove.
  • This groove is advantageously designed without a recess. This is important so that there is no suction in the area of the groove itself and thus any particles that may arise during cutting, in particular chips, cannot get into a recess or even the vacuum source.
  • Recess-free in the context of the present invention is therefore to be understood as meaning those recesses which are used to suck in the workpiece, ie which are connected to a vacuum source.
  • a separate suction device is provided for the particles produced during cutting, which is particularly efficient in connection with a smooth-surfaced groove free of undercuts and recesses with suction from the tool side.
  • the groove is advantageously dimensioned so that the groove width is slightly larger than the cutter diameter and the groove depth is such that the cutter can dip into the groove so far that the cut is made completely with the cylindrical part of the cutter wall.
  • it is possible to provide several grooves for different blanks in a workpiece support surface, but it is particularly advantageous in terms of a high surface quality if a groove is only formed circumferentially according to the contour of the blank, since the particles that arise during cutting are then removed particularly well and completely can be.
  • the workpiece i.e. the sheet metal section from which the blank is to be cut
  • it is particularly advantageous to increase the holding force immediately next to the machining.
  • this takes place in that a greater number of recesses is provided in the immediate vicinity area on both sides of the groove than in the remaining clamping area. If the recesses are designed as bores and these are of the same size, a larger number of bores is advantageously to be provided in this area near the groove than in the remaining area. If recesses of different shapes and sizes are provided then the sum of the cross-sectional areas of the recesses per unit area in the area next to the groove should be significantly greater than in the rest of the clamping area.
  • areas with increased suction force in the vicinity of the groove have proven to be advantageous if they correspond to approximately four to ten times the groove width. If, for example, the groove is 8 mm wide for a 6 mm milling cutter, then the two adjacent areas next to the groove that are provided with increased recesses should each be 16-40 mm wide.
  • an adapter component for this individual adaptation here an adapter plate forming the workpiece support surface of the table, to form, which is arranged on a base table of the machine table, is interchangeable and can be connected to the base table using vacuum clamping technology and can hold the workpiece using vacuum clamping technology.
  • the machine table according to the invention thus consists of the actual base table, which can be standardized and independent of the workpiece, and the replaceable adapter plate to be attached to it, which is adapted to the blank to be produced.
  • the replaceable adapter plate to be attached to it which is adapted to the blank to be produced.
  • the recesses in the base table which are standardized and can be wired to a vacuum source, are only partially continued in the adapter plate, then a part is used The adapter plate is sucked into the recesses in the base table and the workpiece is sucked in via the other recesses in the base table that continue in the adapter plate, ie the sheet metal section is clamped on the adapter plate.
  • the recesses effective in the adapter plate are aligned with recesses in the base table.
  • these recesses in the adapter plate are designed to be widened towards the base table, since a line connection is then also ensured when the adapter plate comes to rest on the base table, shifted by a small amount.
  • a further development of the invention provides that one or more groove-like recesses are provided on the side of the adapter plate facing the base table, which are provided with recesses are wired in the workpiece support surface of the adapter plate and overlap the several recesses in the base table.
  • these groove-like recesses can extend not only in the area below the recesses in the area of the workpiece support surface of the adapter plate, but advantageously also next to them, in order to remove these secondary areas that are still recessed in the base table are provided to branch off further negative pressure capacity.
  • the protal milling machine shown has a milling head 1 which forms the rotary drive for a milling cutter 2 at the lower end of the milling head 1.
  • the milling head is arranged to be movable transversely on a portal 3, which is mounted to be movable longitudinally on a machine table 4.
  • the milling head 1 is lowered so far for milling that the milling cutter 2 can divide a sheet metal section clamped on the machine table 4 into one or more blanks.
  • a preset (programmed) trajectory is driven by appropriate control of the milling head across the portal 4 and control of the portal along the machine table 4, which corresponds to the outer contour and possibly an inner contour of the blank.
  • the machine table 4 consists of a base table 5, which represents the actual load-bearing and functional table and which is equipped on its upper side with an adapter plate 6 which forms the workpiece support surface 7.
  • the base table 5 is constructed as an air table, ie it has a number of fields 8, each of which, as in FIG Fig. 6 shown, are provided with a number of recesses in the form of bores 9, which are line-connected within the table and connected to a vacuum source in the form of a vacuum pump.
  • the adapter plate 6 consists of two plate halves 6a and 6b, which are placed next to one another on the base table 5.
  • the adapter plate 6 consists of aluminum sheet and is 4 mm thick.
  • In the workpiece support surface 7, it has recesses in the form of bores 10, which are distributed over the surface, as well as recesses in the form of bores 11 which extend on both sides of a groove 12 provided in the workpiece support surface 7 of the adapter plate 6.
  • the groove 12 is free of recesses and is arranged in accordance with the contour of the workpieces 13 to be cut out.
  • the groove 12 comprises a total of six equally sized blanks 13.
  • the blanks 13 cannot be seen in the figures because the adapter plate is shown without the sheet metal section to be cut. However, they are numbered accordingly in the figures for better understanding.
  • the groove 12 has a depth of 2 mm so that the milling cutter 2 moves with play within the groove 12 when the blanks 13 are milled out, but can be lowered so far that it only cuts with its side surface.
  • the adapter plate 6 has edge regions next to the blanks 13 which are free of bores. In these edge areas the adapter plate 6 or the two plate halves 6a and 6b is vacuum braced onto the base table 5 as soon as the fields 8 of the base table 5 are connected to the vacuum source.
  • the workpiece itself ie the sheet metal section which is to be divided into the blanks 13, is also clamped on the adapter plate 6 by means of vacuum clamping technology.
  • the bores 10 and 11 are connected to the vacuum source, through the In this area underneath there are holes 9 in the base table 5. Some of the holes 10 and 11 are aligned with the holes 9 in the base table 5.
  • the holes are 10 and 11 formed widening downwards in the adapter plate.
  • groove-like recesses 14 are provided on the underside of the adapter plate 6, which on the one hand form a free space which connects these bores 11, which are arranged in a high surface density, with bores 9 underneath in the base table 5 which, on the other hand, are also arranged outside of the area in which the adapter plate 6 has bores 10, 11. Through these groove-like recesses 14 on the underside of the adapter plate 6, bores 9 in the base table 5 are wired to improve the suction volume, in particular for the bores 11, and thus the holding force.
  • a suction pipe surrounding the milling cutter 2 is provided which, during the milling process, moves directly over the top of the stretched sheet metal section and is sucked off with a high vacuum. Because the closed groove 12 is arranged on the underside of the sheet metal section, where the kerf is produced by the milling cutter 2, a suction flow is created through the groove 12 one that ensures that particles, especially chips, are reliably extracted in this area too.
  • the machine described above is used to produce blanks from sheet metal sections, for example from aluminum sheets, with a thickness of 0.8 to 2.5 mm, as used as blanks for molded automobile body parts.
  • the adapter plate 6 is adapted to the respective blank shape, ie if a blank of a different shape is to be produced, the adapter plate 6 is to be exchanged for a correspondingly different adapter plate with a different groove course.
